摘要

棕榈油厂废水(POME)是印度尼西亚液体废物的主要来源。可作为微藻培养基。Euglena sp.，一种快速生长的微藻，产生高价值的产品代谢物。在本研究中，因其丰富的宏量营养素和微量营养素含量而被用作培养基。此外，POME还具有较高的生物需氧量(BOD)和化学需氧量(COD)。本研究研究了在POME培养基中培养的Euglena sp.处理前后POME中的BOD和COD、生长速率、生物量以及碳水化合物、脂质和蛋白质含量。以CM培养基培养的Euglena sp.为对照。本研究采用的POME培养基浓度分别为0.50%、0.75%、1.00%和1.25%。结果表明，绿藻具有降低BOD和COD的作用。培养基中1.25%的POME处理在去除营养物、生长和营养价值方面效果最好。Logistic模型表明，在1.25%的POME条件下，比生长率(μ)最高，为μ 0.6894 d, R2为0.99。

APPLICATION OF Euglena sp. ISOLATED FROM YOGYAKARTA, INDONESIA ON NUTRIENT REMOVAL FROM PALM OIL MILL EFFLUENT (POME)

Palm oil mill effluent (POME) was the main source of liquid waste in Indonesia. It could be utilized as microalgae medium. Euglena sp., fast-growing microalgae, produces high-value product metabolites. In this research, POME is used as a culture medium because of its rich macronutrients and micronutrient content. In addition, POME also contains high Biological Oxygen Demands (BOD) and Chemical Oxygen Demands (COD). This research was conducted to study BOD and COD in POME after and before treatment, growth rate, biomass and content of carbohydrates, lipids and proteins in Euglena sp. that was cultured in a POME medium. Euglena sp. cultured in Cramer-Myers (CM) medium was used as control. POME medium concentrations used in this research were 0.50%, 0.75%, 1.00% and 1.25%. The results showed that Euglena sp. was able to reduce BOD and COD. Medium 1.25% POME was the best treatment for nutrient removal, growth, and nutritional value. Based on the Logistic modelling, the highest specific growth rate (μ) was achieved in 1.25% POME with μ 0.6894 day and R2 0.99.
